My transform is using an external XML file as a lookup table. Among other
things, the external file contains a list:
...
<files>
<doc>file_one</doc>
<doc>file_two></doc>
<doc>file_three</doc>
...
</files>
Each time the transform runs, the input XML file corresponds to one of the
<doc> elements in the lookup file. The input file name is passed in as a
parameter to the transformation.
<xsl:param name="myself" />
I think the following construction can do the lookup to the external file
and locate the current doc:
.. select="document('lookup.xml')/files/doc[. = $myself]"
but of course this is pointless by itself as I already have the doc name.
What I actually want is to obtain the names of the previous and next docs -
if they exist. There's surely an elegant way to do this, but I don't know
it. What can I do?
How about:
select="document('lookup.xml')/files/doc[. = $myself]"/preceding-sibling::."
and of course:
select="document('lookup.xml')/files/doc[. = $myself]"/following-sibling::."
